IMPROVEMENT IN PORTABLE SFE-PROTECTORS.

' Specification formingpart of Letters Patent No. 131,842, dated October1, 1872.

, accompanying'drawing forming part of this specification, in which-Figure lis a front elevation of my invention, showing the front wall ordoor removed; Fig. 2 is a longitudinal vertical section; Fig. 3 is aview-of the alarm 'mechanism detached; Fig. 4 is a sectional elevation,`showing amodication of my invention; and Fig. 5, a bot-V tom-view of thesame. v

Similar letters of reference in the accompanyingdrawing denote the sameparts.

This invention has for its object to provide M for public use a portableprotector for ordinary re-proof or other safes, which can be used forany safe without particular reference to its construction; and to thisend it consists,

mainly, of a double-walled iron case, sufficiently large to inclose asafe of ordinary size,

and provided on all sides with a space which is to be filled with water.It is also provided with a door, which slides vertically in suitablegrooves, and is operated by rack and pinion,

the turning of which latter operates an alarmgong located in the insideof the case.

`The details of construction and. method of operation will be more fullydescribed hereinafter. i

A represents a rectangular case, constructed l with double iron walls,Vbetween which is a space, a, of any desired width, which is filled withwater. The. space a extends entirely around the case, excepting at thefront, which is protected by a door, B, of similar construction, whichis provided with a water-space, c. The door B slides vertically ingrooves in the front end of case A, and is provided with the verticalrack D, which meshes with the pinion E. This latter islocated on ashaft, F, which runs `across the case A near the front thereof, and is'suitably journaled in its walls. Said a shaft is provided at one endwith a square head, which projects through the case A far enough toengage` the socket of a crank, G, therewith. H represents a disk, whichis 1ocated near one end of the shaft F within the `passes through a slotin the end of said lever,

and causing a spring-hammer to strike the gong K. It will thus be seenthat, as the shaft F 1s revolved in the proper direction, the pinion Eengages with the rack D, and raises the door B. At the same time thepins h of disk H act on the lever I and connecting-rod J in such manneras to strike the gongv at the contact of each of the pins h with thelever, which latter is kept in the position shown in Figs. 2 and 3 byaspring, L. The spaces a o are supplied with water through suitableorifices in 'the upper part of the case, which is also provided withvents for the escape of steam in case of fire. The square head of theshaft F projects into a recess on the outside of case A so that its endis flush with the surface of the same, thereby preventing the revolvingof the -shaft by any person unprovided with the proper key or crank G.In case, however, the door should be opened, the alarm-gong always givesnotice, as it is impossible to tamper with the latter, it being with therack and pinion inside the case A.

This arrangement constitutes a simple as well as efcient protector, andcan be constructed of any desired size. It practically doubles thesecurity of the ordinary safe without a corresponding increase in cost,its construction being comparatively simple and cheap. If desired, thecase can be located on rollers. The safe is held in position within thecaseAby jack-screws I', as shown in Fig. 1.

Fig. 4 shows a modification of my invention, which consists of abottomlcss case, M, which is provided with a water-space, m, and raisedand lowered by a chain or other suitable means, the case resting on thefloor of an apartment when lowered, and inclosing the safe, which restson a water-packed platform, which practically constitutes its bottom.The case M and bottom N are locked together by rods n, which passthrough lugs O on the lower side,

and are in turned locked by a transverse rod, P, which passes throughthe ends of rods n and is secured by a suitable lock, R.

I do not desire to claim the idea of protecting safes by water-spaces,nor the broad idea of inclosing a safe in a separate casing, as safeshave been so arrangedto be lowered into a vault, for instance; but I amnot aware that A, having hollow walls to receive water and an openbottom or side, by which it is adapted to be fitted over an ordinary'fire-prooi' safe, substantially as described, for the purpose speciied.

2. The case A, provided with the verticallysliding door B, operated bythe rack D and pinion E, in combination with the alarm mechanisni,consisting of the disk H, lever I, connecting-rod J, and gong K, as andfor the purposes described.
